SPECIFICATION forming part of Letters Patent No. 533,109,datecl January29, 1895.

Application filed November 24, 1894. $erial No. 529,811, (No model.)

To a whom it may concern:

Be it known that I, HENRY M. WRIGLEY, a citizen of the United States,and a residentof Cincinnati, in the county of Hamilton and State ofOhio, have invented a certain new and useful Attachment forPaper-Box-Ending Machines, of which the following is a specification.

The object of my invention is to provide a gage attachment for paper boxending or setting up machines, whereby the blanks for closing the endsof boxes are automatically stopped in the desired position and thestopgage automatically removed after the end closing blank has been applied,whereby the operation of ending boxes may be rapidly and accuratelyperformed.

The invention will be first fully described in connection with theaccompanying drawings, and then particularly referred to and pointed outin the claims.

Referring to the drawings, in which like parts are indicated by similarletters wherever they occur throughout both the views: Figure 1 is avertical, central sectional view of so much of a paper box setting-upmachine, with my improvements attached, as is necessary to illustrate myinvention. Fig. 2 is a front elevation of the same.

The fixed head, A, with the receptacle, B, for the blanks to be fedunder the head, A, the paste box, C, and the mechanism for automaticallyfeeding the lower blank from the receptacle under the fixed headandsupplying it with the paste, the vertically moving horn, D, with thebase block, E, on its upper end, and the several details shown in thedrawings for automatically feeding the blank,

pasting it, and forcing the blank box against the fixed head, A, aresubstantially the same as in the well known form of machines used forsetting up box ends, and need not, therefore, be specifically described.

As an illustration of the structure to which my improvements areapplied, reference may be madeto the patent to Glazier, No. 515,207, ofFebruary 20, 1894, but the improvement may of course be applied tovarious machines of the same kind. I have selected this one as a typeand will describe my improvements with reference to it. Its applicationthen to other machines of the same general characnot material and theter may be made by any mechanic skilled in the art to which thisinvention relates. Upon the fixed head, A, of this well known structureI erect a supporting standard, F, and upon the front of the fixed head,A, I secure sliding ways or boxes, G, in which the outer legs of thegage frame, H, are fitted to slide and guide it vertically by said strapboxes, G. The gage or stop frame, H, is preferably composed of an upperweb, it, with four dependent legs or members, the outer ones, h, passingthrough the boxes, G, while the inner ones, 71%, pass freely in front ofthe projection upon which the boxes, G, are secured. The frame isstrengthened by the transverse bar, 7L The form of this gage frame, H,is intermediate downwardly projecting members may, if desired, bedispensed with. It is only essential that a stop frame be fitted toslide vertically in front of the stationary head, A..

In the upper end of the standard, F, is pivoted a lever arm, I. Theforward end is coupled in any suitable manner to the vertically slidingstop frame, H, and upon the rear end of the bar, I, is secured a weight,2', the tendency of which is to elevate the forward end of the bar, I,and the gage frame, H, which is coupled to it.

Secured to the vertically reciprocating horn, D, is a transverse bar, J.The means shown for coupling the bar to the horn is an angle bracket, d,the upper angle being perforated to pass the screw bolt, d, which holdsthe block, E, to the horn. WVhen the boltis tightened up, the bracket isheld rigidly to the under projection of the horn. The vertical arm ofthe bracket is also perforated to pass the screw bolt, (1 which couplesthe bar, J, to the bracket, d. In the outer ends of this bar, .I, aresecured rods, j, which extend up above the stationary head, A, and arebent to pass toward the front of the machine and again bent to pass upabove the plane of the lever, I. The upper ends of these rods passthrough a bar, j, the upper ends of the rods, j, being screw threaded,and the bar, j, being held rigidly to the upper ends of the rods, 7', bynuts underneath the bar, j, and nuts upon top of it, which rigidlyfixthe bar to the rods. The bar, passes over the forward end of the leverarm, I, and when the horn, D, is

thrown to the lower position, pulls the forward end of the bar down andbrings the dependent legs of the frame, H, below the front end of thestationary head block, A, so that whenthe lower end blank in thereceptacle, B, is pushed forward, it will be stopped in proper positionto be applied to the box end which is placed upon the movable block, E;but as the block, E, moves upward in the direction of the stationaryhead, A, to force the pasted blank upon the box end, the bar, j, willbe, of course, forced upward, and the weight, 1', will draw the frame,II, upward, so that its lower edge is above the base of the head block,A, and the moment the horn, D,

with its block, E, is started on its downward movement, the box mayberemoved and another one replaced, the operator thus having ample time toremove one box and replace anotherwithout interrupting the continuousmotion of the machine.

In machines of this class it has been contemplated to apply fixed stopsin front of the upper pressure plate in machines in which the upperplate is movable and thelower one stationary, and the lower one movableand the upper plate stationary but such construction was not efficientin a rapidly working machine, because the pressure plates would becompelled to travel some distance before the box with the completed endcould be re-' moved and another one replaced. Now, in my device there isno interruption in the action of the machine anda great many more boxescan be ended in the same time than could be if the stop was fixedpermanently to the upper pressure member.

It is obvious that my improvement can, with slight modifications, beapplied to a box ending machine in which the upper instead of the-lowerpressure block is made movable, in which case the bar,j, should becoupled to the forward end of the lever, I, or thebar, j, might bepassed under the forward end of the rod, and the weight, 2', transferredto the forward end of said bar, I, to hold the lever on top of the bar,j. There may also be other more mechanical changes made without varyingthe principle of my invention and, hence, without limiting myself to thespecific details of construction shown,

hat I claim as new, and desire to secure by Letters Patent, is a v 1. Ina paper box ending machine, the combination of a rest for the end of thebox, a block vertically above said rest, and means for bringing theblock and rest together and separating them, means such as shown forfeeding the pasted blank under the upper pressure block, a gage fittedto slide vertically in front of the upper block, and means such as shownto'hold said gage above the lower face of the upper block as thepressure blocks are brought together, substantially as shown anddescribed.

2. In a box ending machine, the combination of the vertically slidingbox rest, stationary pressure block above it, means such as shown tofeed the pasted end blank underneath the stationary block, the gage, II,fitted to slide in front of the stationary block, a support on top ofthe stationary block for the lever arm, I, the lever arm pivoted in saidblock, the frame secured to the movable box rest, extending up above thestationary block and bearing upon the top of the lever for the purposeof holding the gage in the lower positionwhen the pressure blocks areseparated, and the weight upon the opposite end of the lever to elevatethe frame as the pressure blocks are brought together, substantially asshown and described.

The herein described attachment for box ending machines, consisting ofthe gage, H, the support, F, and lever, I, pivoted in said support, tobe attached to the upper pressure block of the machine,the frame,composed of the bar, J, the rods, j, and upper cross bar, 7", means suchas shown to secure said bar in place, and guides to be; secured to theforward edge of the upper block, combined and arranged substantially asshown and described.
